Timstuff, your colour correction is coming along nicely. I think you need to be somewhere between yours and BmB's as his too much of a brown/yellow tint to it. I know what a complete pain correcting this , and the other star wars movies can be. I can see straight away the problem you are having. It's the cyans because i had the same problem. It's a bi-product of removing the pink tint. In after effects, create a new composition and drag your colour corrected composition into the new one. Then to your composition layer add "effect>colourcorrection>hue/saturation". go to your effects control panel and in the hue/saturation effect select "cyan" in the "channel control" section. now in your colour bar drag the right side triangle a bit more into the green area (you will need to do a bit of trial and error here with how much of the green section you need to add when adjusting this next section). Now adjust the hue wheel towards + until the green tint is gone and it give a more neutral colour (towards blue). Again trial and error here. You can also adjust the saturation of each colour too. Very handy to adjust the reds when colour correcting because skin tones can become a little oversaturated. Just play with the filter with each colour to see how it affects the picture.

Hope this helps :)
